4.3 Drug Warning

PATIENTS WITH HISTORY OF MENTAL ILLNESS OFTEN TOLERATE CYCLOSERINE UNUSUALLY WELL, WHEREAS APPARENTLY STABLE INDIVIDUALS MAY DEVELOP PSYCHOTIC REACTION SOON AFTER INITIATION OF TREATMENT, SOMETIMES BEFORE THERAPEUTIC SERUM LEVELS ARE ACHIEVED.

American Medical Association, Council on Drugs. AMA Drug Evaluations Annual 1994. Chicago, IL: American Medical Association, 1994., p. 1641


Maternal Medication usually Compatible with Breast-Feeding: Cycloserine: Reported Sign or Symptom in Infant or Effect on Lactation: None. /from Table 6/

Report of the American Academy of Pediatrics Committee on Drugs in Pediatrics 93 (1): 140 (1994)


The drug may accumulate to toxic concentrations in patients with renal insufficiency; it may be removed from the circulation by dialysis.

Hardman, J.G., L.E. Limbird, P.B. Molinoff, R.W. Ruddon, A.G. Goodman (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 9th ed. New York, NY: McGraw-Hill, 1996., p. 1165


Because cycloserine is renally excreted, cycloserine may accumulate in patients with renal function impairment, leading to an increased risk of side effects; the medication should not be given to patients with renal function impairment (creatinine clearance of < 50 ml per minute (0.83 ml per second)).

4.4 Drug Indication

Used in combination with up to 5 other drugs as a treatment for Mycobacterium avium complex (MAC) and is also used to treat tuberculosis (TB).


5 Pharmacology and Biochemistry
5.1 Pharmacology

Cycloserine, a broad-spectrum antibiotic, may be bactericidal or bacteriostatic, depending on its concentration at the site of infection and the susceptibility of the organism. Cycloserine works by blocking the formation of these peptidoglycans. By doing this the walls of the bacteria become weak and it results in the death of the bacteria


5.2 MeSH Pharmacological Classification

Anti-Infective Agents, Urinary

Substances capable of killing agents causing urinary tract infections or of preventing them from spreading. (See all compounds classified as Anti-Infective Agents, Urinary.)


Antimetabolites

Drugs that are chemically similar to naturally occurring metabolites, but differ enough to interfere with normal metabolic pathways. (From AMA Drug Evaluations Annual, 1994, p2033) (See all compounds classified as Antimetabolites.)


Antibiotics, Antitubercular

Substances obtained from various species of microorganisms that are, alone or in combination with other agents, of use in treating various forms of tuberculosis; most of these agents are merely bacteriostatic, induce resistance in the organisms, and may be toxic. (See all compounds classified as Antibiotics, Antitubercular.)


5.3 ATC Code

J - Antiinfectives for systemic use

J04 - Antimycobacterials

J04A - Drugs for treatment of tuberculosis

J04AB - Antibiotics

J04AB01 - Cycloserine


5.4 Absorption, Distribution and Excretion

Absorption

Rapidly and almost completely absorbed (70 to 90%) from the gastrointestinal tract following oral administration.


VALUE OF CYCLOSERINE IS ENHANCED BY FACT THAT IT DIFFUSES INTO CELLS & CROSSES BLOOD-BRAIN BARRIER, EVEN IN ABSENCE OF DISEASE.

American Medical Association, Council on Drugs. AMA Drug Evaluations Annual 1994. Chicago, IL: American Medical Association, 1994., p. 1641


When given orally, 70% to 90% of cycloserine is rapidly absorbed. Peak concentrations in plasma are reached 3 to 4 hours after a single dose and are in the range of 20 to 35 ug/ml in children who receive 20 mg/kg; only small quantities are present after 12 hours.

Hardman, J.G., L.E. Limbird, P.B. Molinoff, R.W. Ruddon, A.G. Goodman (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 9th ed. New York, NY: McGraw-Hill, 1996., p. 1165


Cycloserine is distributed throughout body fluids and tissues. There is no appreciable blood-brain barrier to the drug, and CSF concentrations in all patients are approximately the same as those in plasma. About 50% of a parenteral dose of cycloserine is excreted unchanged in the urine in the first 12 hours; a total of 65% is recoverable in the active form over a period of 72 hours.

5.5 Metabolism/Metabolites

APPROX 35% OF ANTIBIOTIC IS METABOLIZED TO AS-YET-UNIDENTIFIED SUBSTANCE.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 1211


5.6 Biological Half-Life

Half-life in patients with normal renal function is 10 hours, and is prolonged in patients with impaired renal function.


Normal renal function - 10 hours. Impaired renal function - prolonged.

USP Convention. USPDI - Drug Information for the Health Care Professional. 16th ed. Volume I. Rockville, MD: U.S. Pharmaceutical Convention, Inc. 1996 (Plus updates)., p. 1131


5.7 Mechanism of Action

Cycloserine is an analog of the amino acid D-alanine. It interferes with an early step in bacterial cell wall synthesis in the cytoplasm by competitive inhibition of two enzymes, L-alanine racemase, which forms D-alanine from L-alanine, and D-alanylalanine synthetase, which incorporates D-alanine into the pentapeptide necessary for peptidoglycan formation and bacterial cell wall synthesis.


EXCRETION OF B-ALANINE & D-BETA-AMINOISOBUTYRIC ACID WAS INCR IN PT WITH TUBERCULOSIS RECEIVING CLINICAL DOSES OF D-CYCLOSERINE.

YASUMITSU T ET AL; BIOCHEM PHARMACOL 25(3) 253-8 (1976)


Cycloserine is inhibitory for Mycobacterium tuberculosis in concentrations of 5 to 20 ug/ml in vitro. There is no cross-resistance between cycloserine and other tuberculostatic agents. While the antibiotic is effective in experimental infections caused by other microorganisms, studies in vitro reveal no suppression of growth in cultures made in conventional media, which contain D-alanine; this amino acid blocks the antibacterial activity of cycloserine. ... Cycloserine inhibits reactions in which D-alanine is involved in bacterial cell-wall synthesis. The use of media free of D-alanine reveals that the antibiotic inhibits the growth in vitro of enterococci, E. coli, Staph. aureus, Nocardia species, and Chlamydia.
